Struct Handle

pub struct Handle<F>(/* private fields */);

Can transfer a unix file handle across processes.

The basic requirement is that you have an object that can be converted into a raw file handle and back. This for instance is the case for regular file objects, sockets and many more things.

Once the handle has been serialized the handle no longer lets you extract the value contained in it.

For customizing the serialization of libraries the HandleRef object should be used instead.

Implementations

impl<F: FromRawFd + IntoRawFd> Handle<F>

pub fn new(f: F) -> Self

Wraps the value in a handle.

pub fn into_inner(self) -> F

Extracts the internal value.

Trait Implementations
